Abstract
The higher order non-homogeneous differential equation in the unit disc was studied.Let f be the solution of non-homogeneous linear differential equation of higher order f(k)+Ak-1(z)f(k-1)+…+A0(z)f=F(z),the coefficients Aj(z)(j=0,…,k-1) and F(z)(not equiv 0)were analyzed in the unit disc,the relationship between the growth order of f and the growth order of F(z) under different conditions was elucidated.
